Sir, I am 35 years old. female.There were symptoms of hyperthyrodism when done the blood test. I took medicine ( PTU 50) for three months. When blood was tested for three times in a year,after this course of medicine, it showed NORMAL. When I consulted an eye specialist recently to check my vision She expressed doubt on thyroid.... Sir, even after showing blood test normal, is there any chances of having thyroid problem ? What should I do now ?
